So, it’s “migrate to Firefox because Google is doing more evil things to the web” day. Because of my need to remain constantly connected to my email, I configured Google Chrome to launch several pages at start up: my personal email, calendar, and drive, my university email, calendar, and drive, Facebook Messenger, and Messages by Google. I’ve found a way to configure Firefox to load these pages at browser start up, however this option also loads this set of pages every time I open a new FF window, which is sub-optimal as I like to keep the first window free of any other junk while using subsequent windows for browsing. Might anyone have any suggestions as to how I might get the desired functionality (launch Firefox and get a window with the above tabs, but not have them re-spawn every time I open future FF windows)? Thanks.
